Zero measure spectrum for multi-frequency Schrödinger operators
(2022)Building on works of Berthé–Steiner–Thuswaldner and Fogg–Nous, we show that on the two-dimensional torus, Lebesgue almost every translation admits a natural coding such that the associated subshift satisfies the Boshernitzan criterion. As a consequence, we show that for these torus translations, every quasi-periodic potential can be approximated ... -
Zinc Oxide Particles Induce Activation of the Lysosome–Autophagy System
(2019)Metal-oxide-based materials are highly versatile and used in a wide variety of applications ranging from medical technology to personal care products. Generally recognized as safe by the US Food and Drug Administration, zinc oxide (ZnO) has been increasingly used in pharmaceutical, cosmetic, food, and commodity chemical industries. As a result, ... -
ZipA Uses a Two-Pronged FtsZ-Binding Mechanism Necessary for Cell Division
(2021)In most bacteria, cell division is centrally organized by the FtsZ protein, which assembles into dynamic filaments at the division site along the cell membrane that interact with other key cell division proteins. In gammaproteobacteria such as Escherichia coli, FtsZ filaments are anchored to the cell membrane by two essential proteins, FtsA and ZipA. ... -

β-YbAlB4: A Critical Nodal Metal
(2012-10)We propose a model for the intrinsic quantum criticality of β-YbAlB4, in which a vortex in momentum space gives rise to a new type of Fermi surface singularity. The unquenched angular momentum of the |J=7/2,mJ=±5/2⟩ Yb 4f states generates a momentum-space line defect in the hybridization between 4f and conduction electrons, leading to a quasi-two-dimensional ... -
λ group: Using Optics to Take Group Data Delivery in the Datacenter to the Next Degree
(2014-02-17)The increasing number of datacenter applications with heavy one-to-many communications has raised the need for an efficient group data delivery solution. This paper presents an unconventional clean-slate architecture called λ group that uses optical networking technologies to enable ultra-fast, energy-efficient, low cost, and highly reliable group ... -
ΛΛ Correlation Function in Au+Au Collisions at √sNN=200 GeV
(2015)We present ΛΛ correlation measurements in heavy-ion collisions for Au+Au collisions at √sNN=200 GeV using the STAR experiment at the Relativistic Heavy-Ion Collider. The Lednický-Lyuboshitz analytical model has been used to fit the data to obtain a source size, a scattering length and an effective range. Implications of the measurement of the ΛΛ ... -
ρ0 photoproduction in AuAu collisions at √sNN=62.4 GeV measured with the STAR detector
(2012)Vector mesons may be photoproduced in relativistic heavy-ion collisions when a virtual photon emitted by one nucleus scatters from the other nucleus, emerging as a vector meson. The STAR Collaboration has previously presented measurements of coherent ρ0 photoproduction at center of mass energies of 130 GeV and 200 GeV in AuAu collisions. Here, we ...
